?? In the actual infiltration, when we found that there is a file upload place, we will try all the way to Webshell upload, as long as you can upload Webshell, it shows that this infiltration at least successful general, follow-up on the Webshell to see the status of access to the next step of operation. For file upload vulnerability protection, mainly divided into the following two categories: White list restrictions and blacklist restrictions, for the blacklist limit, we only need to find some

Instance: web servers that use routers to bypass DDoS Defense (1) Recently, I have been studying DDOS attacks. As we all know, DDOS attacks are commonly called distributed denial-of-service (DoS) attacks. Attackers generally send a large number of packets to the ports opened by the target host through a large number of slave hosts, the data on the target host is congested, and the system crashes when resources are exhausted. In my test, I found that i

natural example. I directly used a statement to bypass background login verification and enter the background. At that time, I thought it was quite good, so I went deep into its principle and had a certain understanding of it. Okay. Let's get started with the question. Once we mentioned that the website's background management system is directly accessed without background login verification, we can think of a classic universal password: \ 'or \' = \

1. Use encoding technologies such as URLEncode and ASCII code. For example, if or 1 = 1, % 6f % 72% 20% 31% 3d % 31, and Test can also be CHAR (101) + CHAR (97) + CHAR (115) + CHAR (116 ). 2. Use spaces to bypass such as two spaces to replace one space, use Tab to replace spaces, or delete all spaces, such as or swords = 'swords. Due to the loose nature of mssql, we can remove spaces between or words without affecting the operation. 3. Use string judg

First, I would like to explain that some of the bypass methods are not original. Here I just want to make a brief analysis and explain them. In addition, I will also take measures on the Internet to bypass anti-injection measures. The general content is similar to coding. Here are several references: 1, for example, common URL encoding. 2, ASCII encoding. 3. Space bypas
